Leveraging triplet loss and nonlinear dimensionality reduction for on-the-fly channel charting

no code implementations4 Apr 2022 Taha Yassine, Luc Le Magoarou, Stéphane Paquelet, Matthieu Crussière

Channel charting is an unsupervised learning method that aims at mapping wireless channels to a so-called chart, preserving as much as possible spatial neighborhoods.

Dimensionality Reduction

Deep learning for location based beamforming with NLOS channels

no code implementations29 Dec 2021 Luc Le Magoarou, Taha Yassine, Stéphane Paquelet, Matthieu Crussière

Massive MIMO systems are highly efficient but critically rely on accurate channel state information (CSI) at the base station in order to determine appropriate precoders.

Channel estimation: unified view of optimal performance and pilot sequences

no code implementations11 Feb 2020 Luc Le Magoarou, Stéphane Paquelet

In this setting, the problem of designing optimal pilot sequences of smallest possible size is studied for any parametric channel model.
